DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are of exemplary embodiments only, and arenot intended to limit the scope, applicability or configuration of theinvention in any way. Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

Referring FIG. 1, the present invention relates to a pressure reservoirstructure for use in water comprising a main float 1 on the water, andthe main float 1 has a plurality of pressure reservoir modules 2 havingan air chamber 21 including a piston 22 and an elastic member 23 (aspring being shown). The lower section of the piston 22 is connected toa piston rod 24 having one end connected to an enlarging device 4connected to a moving rod 20 (as shown in FIG. 2) containing a sub floatbody 25 (a hollow floating ball being shown). The air chamber 21 isprovided with an air inlet uni-direction valve 26 and an air outletuni-direction valve 27. When wave is generated, the sub float body 25moves the piston 22 to move upward and air flows out from the outlet 27via a tube 28 to a storing cylinder 3. The cylinder 3 includes a hollowcylinder 31, an uni-direction air inlet 32, an uni-direction air outlet33, a pressure plug 34, an elastic member 35. Air continuous enters thecylinder 3 until a preset value. The recessing of the pressure willgenerate wind energy.

The individual cylinders 3 can be connected in parallel to the storingbody 5. As shown in FIG. 4, the air chamber of the two pressurereservoir modules are connected in series at the storing cylinder 3. Asshown in FIG. 5, the storing cylinders 3 are respectively connected inparallel with the storing body 5, wherein the right hand side module isconnected to the main body 5 with a connection tube 50. As shown in FIG.6, the two storing bodies are connected in series, that is the left handside module of the storing cylinder 31 is connected to the storingcylinder 31 via a connection tube 36. This structure is similar to thatof FIG. 7, but in FIG. 7, it shows three storing cylinders connected inseries to the storing body 5.

As shown in FIG. 3, the enlarging device 4 is a fixing frame 41pivotally mounted to a parallel shafts 43, 49 and a pair of parallelgear strap 42, 48 are provided to the enlarging device 4. The gear strap42 is fixed to the moving rod 20, and the moving rod 20 passes throughthe through hole 11 at the bottom of the main float 1. The gear strap 48is secured to the piston rod 24, and the rotating shafts 43, 49 arerespectively pivotally connected to a concentric small, large gears 44,45, 46, and 47. The gear strap 42 and the small gear strap 44 areconnected, and the small gear 44 drives the concentric large gear 45 torotate. The large gear 45 is connected to the small gear 46, and thesmall gear 46 drives the concentric large gear 47 to rotate. Large gear47 is connected to the gear strap 48 and when the gear strap 42 movesupward the gear strap 48 is moved upward so as to accomplish multipletimes of force. That is the piston 22 produces larger compression forceso as to generate better pushing force. The simple structure does notneed the enlarging device 4 and the sub float body 25 is directlyconnected to the piston 22. However, the effectiveness is restricted bythe environment, and the compression is lesser.

The main float 1 is applied on the shore via connecting device, forinstance, oil drilling platform. When wave is generated, the sub floatbody 25 drives the piston 22 to move upward and the piston 22 will berestored by the elastic member 23. The air hole of the air chamber 21can be a through hole (as shown in FIG. 7) or a tube bent upward. Whengas continuous to enter the storing cylinder 3, the air pressure of thecylinder 31 is increased. The pressure plug 34 is elevated until apredetermined pressure valve, the air pressure will be released via theair outlet 33 to a turbine (not shown), and the high pressure gas willdrive the turbine to rotate at a high speed. This will convert intoelectric power or out power to be output. The storing float 3 is formedfrom a series of floats in parallel or in series. Thus, the main float 1may not be restricted to one set. The length, the width, the height ofthe float body are varied based on the environment and weather. Ifconnection device is provided, the main float 1 will move up and down.In accordance with the water level of the tide. The structure inaccordance with the present invention will always on the water surfaceand therefore the longevity of the structure is extended.

In accordance with the present invention, the structure does notrestrict only to electricity generation but the energy thus obtained canbe converted into other form of energy for application.

It will be understood that each of the elements described above, or twoor more together may also find a useful application in other types ofmethods differing from the type described above.

While certain novel features of this invention have been shown anddescribed and are pointed out in the annexed claim, it is not intendedto be limited to the details above, since it will be understood thatvarious omissions, modifications, substitutions and changes in the formsand details of the device illustrated and in its operation can be madeby those skilled in the art without departing in any way from the spiritof the present invention.
